SAN D-BOX FOR CARS.

SPECIFICATION forming part of Letters Patent No. 473,070, dated April 19, 1892.

Application filed January 6, 1892. Serial No. 417,191. (No model.)

To all whom it may concern:

Be it known that I, HERBERT H. HENNEGIN, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Sand-Boxes for Cars, of which the following is `a full, clear, andexact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in sand-boxes for carsg and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.

Inthe drawings, Figure l is a vertical longitudinal section of a railway-earrwith parts broken away and having my invention applied thereto. Fig. 2 is a vertical longitudinal section of my invention having the various parts attached to the same. Fig. 3 is a top plan view of the gearing which I employ in carrying out myinvention, partially broken away. Fig. 4 is a perspective view of the bearing which is secured vto the inner surface or oor of the car. Fig. 5 is a cross-section taken on the line oc oc of Fig. 3, showing the construction of the shaft upon which one of the double gear-wheels are mounted and the means for operating said gear; and Fig. 6 is a front elevation of the separable gear-wheel which I employ and which is carried by the shaft upon which the drive-wheels'of the car are mounted. Y

My invention has for its'object to provide the ordinary street-railway car with a sanding device for supplying sand to the rails upon which the car moves in front of the wheelsof the same. It is preferably located under the platform of the car, and is operated by a hand-lever or other mechanical contriv-l ance and in easy reach of the operator. The sanding devices heretofore employed for this purpose are such that they will not always feed the sand to the track when it is necessary; but, on the contrary, the said sand will choke in the chute which supplies the .said sand to the track, and consequently another contrivance must necessarily be employed to release the sand so choked in the chute. Hy invention is especially constructed y to overcome this objection by employing the arrangement and construction of parts as I shall now proceed to describe. In practice I employ two of the devices, as hereinafter described, one on each side of the car; but as they are similarly constructed and operated ina like manner I shall only proceed to describe one of them in detail.

Referring to the drawings, 1 represents the car-body, 2 the platform of the sa1ne,-and 3 the shaft of one of the sets of wheels upon which the said car-body is mounted in the usual manner. To said shaft 3 is rigidly secured a gear-wheel 4, which is united to said shaft and is detachable therefrom, as I shall now proceed to describe. Said gear-wheel-4 is divided into two parts 5 and 6, the said part-s being hinged together by means of a hinged joint 7 and the opposite ends of said partsV united by means of a bolt 8, passlng through suitable holes formed in the ears 9 of said sections. By the employment of the construction as above described the said gearwheel can be easily placed on the shaft and removed from the same without in any Way disconnecting any of the parts of the ordinary car.

10 represents a bearing, which is secured to the under surface of the floor of the car 'adapted to support a rotating shaft 11, which shaft is comparatively short and upon the ends of which are mounted and 'keyed to the same bevel gear-wheel l2 and gear-wheel 13, as best shown in Fig. 3.

14 represents a chain, which passes over the gear-wheel 4 and also over the gear-wheel 13, forming a connection between the shaft 3 of the car and the short shaft 11. By the above construction the bevel gear-,Wheel l2 will under all circumstances revolve or rotate when motion is imparted to the axle or shaft 3 of the car, but said bevel gear-wheel l2 will not impart motion tothe sanding device until the mechanism is operated, as hereinafter more specifically referred to.

15 represents a boX or receptacle having converging sides and having its upper edge secured in any manner to the under surface of the bottom of the platform 2 of the car, premising, however, that a suitable opening is formed in the platform, and a door, such as 16,

ICO

corresponding in size to said opening, is adapted to cover the top of said box or receptacle. Within said box or receptacle is placed the sand to be suppliedv to the .trackrail. The bottom 17 of said box or receptacle has an opening 18, which opening communicates with a trough 19 of suitable length, and formed in the bottom of the said trough,

near the end of the same, is an opening 20,

which communicates with the chute 21 or exit for the sand.

.22 represents a shaft, which is mounted within the trough 19, and -secured to said shaft or to that portion located within said troughis a conveyer 2 3, which when rotated 1n the proper direction will cause the sand to be fed from the box or receptacle 15 to the chute 2l. Should there be any lumps in the sand contained in the box 15, the conveyer above described will break the same, and at the same time convey the sand, as above described. The projecting end of the shaft 22 is provided with a feather 24, which allows the bevel gear-wheel 25 to he moved in a longitudinal direction and at the same time lock the said gear-wheel against rotation independent vof said shaft. Said beveled gear-wheel 25 when in the position as shown in Fig. 2 of the drawings Will not be rotated by the mechanism, as previously, described; but when said gear-wheel is moved to the right, referrlng to the said drawings and better illustrated in Fig. 2, the shaft -22 will be rotated,

the said bevel-gear being brought in connection with the beveled gear-wheel upon one end of the shaft 11.

The beveled gear-wheel 25 is provided with a ianged extension 26, forming a neck 27, around which the forked end of the rod 28 is placed.

29 represents an operating-lever, which is fulcrumed in the platform 2 of the car, and to the short arm of said lever is loosely attached the opposite endof the rod 28, or, rather, that end of said rod opposite to the forked end on the same. 30 represents the forked end of the said rod, as better illustratedl in 12, carried Fig. 5, by which construction the lever 29,whenY pulled to the right, referring to Fig. 1, the bevel gear-wheel 25 will be released from contact with bevel-wheel 12, and consequently Ano motion will be imparted to the conveyer 23. However, when it is desired to throw the gearing in contact with one another the lever 29 is pushed in the opposite direction, as shown in Fig. 1, and motion imparted to the conveyer 23. As the sand is only conveyed to the track under certain circumstances and when it becomes necessary, I find it practicable to employ certain mechanism, as hereinafter described, to normally-press upon the bevel gear-wheel 25 and prevent the said gear-wheel from being rotated only when it is necessary.

31 represents a collar, which is secured to the extreme end of the shaft 22, and interposed between said collar and the bevel geari Wheel 25 is a coil-spring 32, which accomplishes the object as desired.-

It will be readily understood that when itis desired to convey sand to the track the coilspring 32 will be compressed So long as the lever 29 is pushed in the direction as shown in Fig. 1.

I do not wish to limit myself to the precise construction as above described, as the same' may be changed or modified without departing from the true nature of my invention.

Having fully described my invention, what I claim is-f 1. A sand box for cars, consisting of a trough, such as 19, in communication with said box, a conveyer, such as 23, located within the said trough and in contact with the sand contained in said box, a gear-wheel `mounted upon the axle of the car, suitable ge'laring between said gear-wheel and conveyer for imparting motion tothe saine, and means for disconnecting said gearing, substantially as set forth.

2. A sand-box for cars, consisting of a trough, such. as 19, attached to the lower surface or bottom of said box and in communication with the saine, a shaft,'such as 22, mounted within the said trough, a conveyer 23, secured upon the shaft 22, for conveying IOO for throwing the bevel gear-wheels-25 and 12v in and out of gear, substantiallyv as set forth.

3. A sand-box for cars, consisting of a trough, such as 19, attached to the lower surface or bottom of the said box and in communication with the same, a shaft, such as 22, mounted within said trough, a conveyer 23, mounted yupon said shaft, a bevel gearwheel 25, loosely mounted vupon said shaft and adapted to be moved in alongitudinal direction, a flanged extension 26, formed with the said gear-wheel. 25,a lever, such as 29,fulv crumed in the bottom of the platform of the car, a rod, such as 28, connected to the said lever, a fork, such as 30, formed on the opposite end of the said rod, spanning the neck 27 of said extension, and means for imparting motion from the axle of the car to said conveyer, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
